<p>A method of obtaining fixation of an animal aortic valve intended for implantation, including subjecting the aortic valve (13) to a tanning fluid at a differential pressure across the valve leaflets (21 and 25) in a direction to urge the valve leaflets closed and with the tanning fluid tending to distort the aortic valve. The differential pressure across the valve leaflets is greater than zero and less than about four mm Hg. An insert (17) restrains the valve (13) against substantial distortion during the time the valve is subjected to the tanning fluid.</p> |
